MM#003 Major Flare Watch
by Max Millennium Chief Observer 10 Nov '13

10 Nov '13

Dear RHESSI Collaborators, The current level of solar activity is high. Yesterday's target region (NOAA 11890) was responsible for a X1.1 flare on 10-Nov-2013 at 05:14 UT. The polarity separation line within the delta-spot in the region's intermediate portion has strengthened significantly since the previous message. Due to the increase in activity of the target region, the current MFW will continue for at least the following 24 hours. Moderate activity is expected with a chance of a further X-class event. The position of NOAA 11890 on 10-Nov-2013 at 18:10 UT is: S11W25, ( 404", -236" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, The current level of solar activity is low. The largest event since the previous message (a C2.6 flare on 9-Nov-2013 at 06:47 UT) was released by the target region, NOAA 11890. The delta-spot remains in the region's intermediate portion, but no significant activity has been released in the past 24 hours. The MFW will continue for the following 24 hours, but will likely be called off with tomorrow's message if the current levels of activity continue. Further C-class activity is expected with a chance of an isolated high M-class flare. The position of NOAA 11890 on 9-Nov-2013 at 19:50 UT is: S11W13, ( 214", -241" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, The current level of solar activity is high. NOAA 11891 was responsible for C-class activity and a M2.3 flare on 8-Nov-2013 at 09:28 UT, but its main delta-spot has separated, leaving a much smaller delta spot in the intermediate portion of the region. Yesterday's target region (NOAA 11890) was responsible for further C-class activity and a X1.1 flare on 8-Nov-2011 at 04:26. The main spots within the region show fragmentation, but the delta-spot within the region's following portion has increased in size, and its polarity separation line has strengthened. The current MFW will continue for at least the following 24 hours. Further M-class activity is possible, with a chance for a low X-class event. The position of NOAA 11890 on 8-Nov-2013 at 17:50 UT is: S11W00, ( -2", -244" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, The current level of solar activity is moderate. A new small spot group (>50uhemi) is emerging with a delta spot (designated NOAA 11891). So far, the region was responsible for several C-class events. Yesterday's target region (NOAA 11890) was responsible for further C-class activity and two M-class events since the previous message: a M2.3 on 7-Nov-2013 at 3:40 UT and a M2.4 on 7-Nov-2013 at 14:25 UT. The shearing motions within 11890 appear to have subsided, although two positive umbrae within the large elongated negative following spot still appear strong. The current MFW will continue for at least the following 24 hours. Further M-class activity is possible, with a chance for a high M-class event. The position of NOAA 11890 on 7-Nov-2013 at 18:40 UT is: S11E14, ( -227", -244" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, The current level of solar activity is moderate. Yesterday's target region (NOAA 11890) was responsible for a number of C-class events and a M3.8 flare (on 6-Nov-2013 at 13:46 UT) since the previous message. The main delta spot appears less sheared than before, but both umbrae remain strong. The MFW will remain in effect for at least the following 24 hours. Further high M-class activity is likely, with a chance for an isolated X-class event. The position of NOAA 11890 on 6-Nov-2013 at 19:00 UT is: S11E26, ( -411", -242" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, The current level of solar activity is high. Today's target region (NOAA 11890) has just released a X3.3 flare. The main delta spot shows extensive shearing along its polarity separation line, which now extends along the majority of the spot length. Further high M-class activity is expected, while a further X-class event is possible. The position of NOAA 11890 on 5-Nov-2013 at 23:00 UT is: S09E36, ( -567", -204" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

MM#009 Default HESSI Target
by Max Millennium Chief Observer 05 Nov '13

05 Nov '13

Dear RHESSI Collaborators, The current level of solar activity is moderate. Over the previous 24 hours, yesterday's target (NOAA 11890) was the source of a number of C-class events and a M2.5 flare on 5-Nov-2013 at 08:18 UT, followed by a C8.0 flare at 11:58 UT. The region is now classified as a beta-gamma-delta magnetic configuration. The M2.5 and C8.0 events occurred over the region's mixed polarity spot, which is present in the trailing portion. The spot shows some evidence for shearing within its polarity separation line, and has not weakened significantly over the previous 24 hours. Further high C-class activity is expected, while further M-class activity is possible. The position of NOAA 11890 on 5-Nov-2013 at 18:00 UT is: S09E39, ( -604", -202" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

MM#009 Default HESSI Target
by Max Millennium Chief Observer 04 Nov '13

04 Nov '13

Dear RHESSI Collaborators, The current level of solar activity is low. Yesterday's target (NOAA 11884) has not produced significant activity since the previous message. Furthermore the region has continued to decay and only shows weak evidence for a gamma magnetic configuration. A new region, designated as NOAA 11887, is emerging near N20E10, but currently exhibits a beta magnetic configuration. On the other hand, NOAA 11890 exhibits the largest spot area (660 uhemi) and the most complex spot configuration (beta-gamma/Ehc). Also, the region appears to be the most active in X-rays. High C-class activity is possible, with a chance for an isolated low M-class event. The position of NOAA on 4-Nov-2013 at 16:45 UT is: S10E53, ( -760", -208" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 1884 was the source of two M-class events in the past 24 hours - M1.6 at 11/02/22:21 UT and an M4.9 at 11/03/05:22 UT. 1884 is classified as an E-type/beta-gamma-delta region. The magnetic delta configuration is currently weakening but the region continues to have the potential to produce another M-class event in the next 24 hour period. NOAA 1890, S09E66, is a large E-type/beta-gamma region that is also capable of producing an M-class event. 1890 was the source of a C9.9 event at 11/03/16:28 UT. 1884 will remain the target region for at least another 24 hours. The position of NOAA 1884 on November 03 at 14:00 UT is: S12W21 (Solar X = 340", Solar Y = -264) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 1884 was the source of an impulsive M6.3 major event at 11/01/19:53 UT. 1884 is maintaining its E-type/beta-gamma-delta sunspot group. C-class events are certain with an excellent chance of another isolated M-class event in the next 24 hour period. The position of NOAA 1884 on November 02 at 14:00 UT is: S13W09 (Solar X = 147", Solar Y = -226") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
